Filed: 1986-08-18
Abstract: PURPOSE:To lengthen the service life of a thermal head, by making a modification control of print pattern for each print information such that the operation is not concentrated extremely onto any heating dot constituting the thermal head. CONSTITUTION:When it is judged that the count of a sheet number counter has reached a print pattern rotary period N, previous print pattern is rotated by 180 deg. and the sheet number counter is cleared than ticket issue process is executed based on a new print pattern provided upon the rotation of 180 deg..
